Problems solved by technology

[0003] 1. It is very difficult to make large-scale roller shafts. The extrusion rollers of large-scale roller presses (or high-pressure roller mills) can weigh up to 60-70 tons, have a diameter of up to 2.4 meters, and a length of up to 5 meters. Forging or Casting production equipment and process requirements are relatively high
[0004] 2. It is difficult to guarantee the product quality of large rollers. When the production equipment and process of rollers are difficult to guarantee, the quality of products is difficult to be stable. As the core component, the shaft bears very harsh loads and working conditions. If there is a quality problem with it, it is likely

Example Embodiment

[0025] Example 1:

[0026] Take the squeeze rollers of the roller press (or high-pressure roller mill) with a diameter of 2 meters as an example. The rollers of the 2 meter series include 20060, 20080, 200100, 200120, 200140, 200160 (Note: 200 means squeeze roller The diameter is 200cm, and the last numbers 60, 80, 100, 120... indicate the width of the squeeze roller, the unit is cm).

[0027] If you press figure 1 For the production of the traditional integral roller structure, it is necessary to organize the production of 20060, 20080, 200100, 200120, 200140, 200160 rollers, and they cannot be borrowed from each other. The diameter of the 200160 rollers can reach 2 meters, and the width of the extrusion surface can be Up to 1.6 meters, such a large roller has high requirements for manufacturing equipment and technology, and it is difficult to guarantee the mechanical performance. It is difficult to achieve serialization, modularization and large-scale production of the roller, a...

Abstract

The invention discloses a roller shaft combined with a roller press and a high-pressure roller mill, and relates to a roller shaft of a roller press and a high-pressure roller mill, including a shaft core and a shaft sleeve, and the shaft sleeves are at least two The combination sleeve is arranged and combined along the axial direction. The invention is a roller press and a high-pressure roller mill that are less difficult to manufacture, can effectively guarantee product quality, have interchangeability between different models, have a short production cycle, and can realize serialization, modularization, and large-scale production. Squeeze roller shaft.

Description

technical field [0001] The invention relates to a squeeze roller shaft of a roller press (or called a high-pressure roller mill). Background technique [0002] With the development of grinding technology in recent years, the roller press (or high-pressure roller mill) based on the principle of material bed grinding has been widely used in cement clinker, cement raw meal, slag, steel slag, iron ore, chemical and other powders. In the field of grinding, obvious energy saving effect has been achieved. However, with the widespread application of roller presses (or high-pressure roller mills) and the serialization of specifications, especially after large-scale, the extrusion roller shafts of traditional roller presses (or high-pressure roller mills) will face the following question: [0003] 1. It is very difficult to make large-scale roller shafts. The extrusion rollers of large-scale roller presses (or high-pressure roller mills) can weigh up to 60-70 tons, have a diameter o...
